IMPROVEMENT IN STOP-COCKS.

Specification forming part of Letters Patent No. 194.336, dated August 21, 1877; application filed June 25, 1877.

To all whom it may concern:

Be it known that we, SAMUEL M. DENNIS- TO: and CHARLES SIMMONS, of Prescott, Yavapai county, Territory of Arizona, have invented a new and Improved Stop-Cock, of which the following is a specification:

Figure l is a side elevation, and Fig. 2 is a detail view, of the fastening device.

Our invention consists in the combination, with a stop-cock, of a splitthreaded tube having a T-shaped head, which may be inserted in a hole in a can, and upon which the stopcock may be screwed.

The object of our invention is to provide a device by means of which stop-cocks may be readily attached to metallic cans.

1n the drawing, A is a tube, which is threaded externally, and is provided with a T- shaped head, B. The said tube is split longitudinally, so as to divide the T-shaped head transversely through its center. The head B is placed inside the can by putting the two parts of it together parallel to each other,

the side of the can between the head B and packing-ring 0.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- The combination of the split and threaded tube A, having the T-shaped head B and the stop-cock D, substantially as shown and described.
